Steamed muffins

Use any off the self muffin mixture, using powder milk where milk is required and carry oil in a small sealed container. You will need a double boiler of some description. They are easy to make using disposable aluminium baking trays from the super market. Cup cake moulds are handy to have as well – either the disposable paper type or a non-stick silcone type, although you can eat this straight from the bag.
